This would be my major concern. The cord looks undamaged, however that might have happened! But without the rubber protecting the cord, it's a flat, possibly a blowout, waiting to happen. And I would not rely on Shoe Goo to repair a cut that big. (I have successfully repaired small cuts that way, though.)
